Really nice write-up. Interesting observation/experience with the new Plaid (Brembro) brakes, but I have to wonder if he's talking more about braking on the track or just everyday driving? Besides, any Plaid owner can simply change out the brakes if they really want...it will cost $4k+ to get better, driller/slotted rotors & larger calipers/ceramic brake pads, but it can be done. I think for most people driving the Plaid (who are not tracking it like me for example), the oem brakes may be quite sufficient for everyday driving + some occasional spirited driving. Thoughts?
Typically, big brakes will cost more, I'd think close to 10K and more for ceramics...
But I have no doubt that existing brakes are as good as they can be for a daily driving, except track, and maybe canyon runs.
Bigger brakes don't buy you better stopping times, as they're contact patch limited. They buy you more termal capacity to withstanding track temperatures longer
I've been track junkie, so I know a bit on this subject; it used to be the case that brakes were about twice as strong as the engine.
But that was then, and this is now. I think that shop owner is under influence of that old 2x rule. To him, brakes don't feel as strong as they should, compared to acceleration. Because acceleration moved forward, but brakes haven't. Today's Motortrend article/test has shown that max G-s generated have been almost equal in acceleration and breaking. Which again means they're tire/contact-patch limited. Tesla has pushed motors to the limits equal of brakes, but can't do anything more on the brakes for now; until tire technology progresses, or they put massively wider tires - which won't happen.
So, if you want the best, upgrade brakes for more termal capacity, so you can occasionally track the car - but no one in their right mind will seriously track Plaid - it's too big.
Having said this, is the shop owner right that people will die? Very likely. Some people will just not compute enough of the accelaration/speed/brakes ratios to be safe. But should this mean that Tesla shouldn't have produced such a powerful car? I feel there is something to be said re free will...
I know that when my 10 year old is 16-20, he WON'T drive this car. My daughter, we'll see, maybe... Wait, is this sexism?
